ANTISLIPPING DEVICE.

Application filed February 17, 1923. Serial No. 619,733.

To all whom it may concern: Figure 4 is a fragmentary view, illus- Be it known that I, JOHN J. EHMEN, a trating the manner'in which the hook encitizen of the United States, and a resident gaging loops are associated with the clamp. of Clayton, in the county of" Adams and Referring to the drawings wherein for 5 State of Illinois, have invented certain new the sake of illustration is shown the pre- 55 and useful Improvements in Antislipping fcrred embodiment of. the invention, the Devices, of which the following is a specifinumeral designates generally a wheel cation. which may be an automobile wheel and This invention relates to an anti-slipping which preferably includes spokes 11 and a 10 device for use with wheels and is particupneumatic tire 12. so

These anti-slipping devices are may be readily applied to or taken from the all of identical construction and each inwhcel and which When on the wheel holds cludes a chain 16 extending transversely the anti-slipping chains or traction elearound the tire and having end links 17 ments in proper position preventing slapand 18, each of the end links being pro- 20 ping movement or other undesirable movevided with a pair of apertured eyes, desig- 7o ments of the same and also preventing the nated at 19 and 20 respectively. The memchain from injuring the tire or other elebers of each pair of eyes are formed by ments of the vehicle and holding it in the bending the terminals of the wire which field or sphere of most efficient action. constitutes the end link into circular form 2 Another object is to provide a device of and themembers of each pair are also arthis character with these advantages and ranged in spaced relation and in axial alinealso being of simple and durable construcment. Ahook, designated generally at 21, tion, reliable in operation and susceptible is associated with eachend link 17, the fiat of convenient and comparatively inexpenshank 22 of the hook being provided with 30 sive manufacture from materials and with a series of openings 23 adapted to be selecfacilities ordinarily available. tively alined with the apertures of the eyes Other objects and advantages of the in- 19. A cotter pin 24 is inserted through the vention reside in certain novel features of eyes and through the alined opening of the the construction, combination and arrangeshank of the hook and serves to pivotally 35 ment of parts which will be hereinafter connect the hook 21 with the end link 17. more fully described and. particularly Washers 25 may be associated with the cotpointed out in the appended claims, refertcr pin, as shown in Figure 2, if desired. A ence being had to .the accompanying drawsnap hook 27 is connected with the end link ings forming part of this specification, and 18, .the snap hook having an attaching 40 in which: r frame 28 engaged with the eyes 20 of the Figure 1 is av fragmentary view in side end link18. A, split sleeve 29 is associated elevation showing a portion of an automowith the attaching frame 28 to prevent acbile wheelequipped. with the anti-slipping cidental displacement of the hook 27. devices constructed in accordance with the A spoke connector or clamp, designated 45 present invention; generally at 30 is provided for each chain Figure 2 is a, perspective view, showing 16. Each of the clamps 30 comprise two the anti-slipping chain and the associated sections, designated at .30 and 30", each hooks; 7 section being made up of a singlepiece of Figure 3 is a similar view of the. clamp wirelooped or. doubled upon itself to pro- I a or sp ke connect-9r; and a u per an lawn the s sti l? 59 section 30 being designated at 31 and 32 and the arms of the section 39 being designated at 33 and 34. The bights of the loops are indicated at 35 and 36, and these bights serve to connect the upper and lower arms. Also the portions of the sections 30 and 30 adjacent the bights 35 and 36 are offset or extended angularly. with respect to the main portions of the sections sothat the bights together with the adjacent offset portions of the arms provide spaced bolt seats or sockets adapted to coact with'a' bolt 37 and nut 38 for securing the clamp on the spoke as will presently appear. The terminals or free ends. of the length, of wire which makes up each section are bent to, form apertured; ears, tl'1e apertured ears of the, section 3O being designatedat 40 and the apertured ears, of the section 30* being designatedat 41... These apertured ears are arranged in. axial alinement, being interfitted for this purpose and through the alined openings of the ears 40 and41- a hinge pin 4-2 is inserted, the hinged pin being suitably secured in, position as by means of a nut or the like and washers 43 being interposed between the nut in the adjacent eye at one end and the head of the hinged pin and the eye adjacent thereto the other end.

I-look engaging loops, indicated at 45 and as, are associated with the sections 30 and 30', respectively, of the clamp. The loops 45 and 46 are constructed of resilient wire and the loo-p 45. has extensions 47 which extend from the loop down around the lower arm 32 and then up. around the upper arm 31, the terminals of the extensions bearupon the upper side of the lower arm 32, as indicated at 48. In this manner the extensions completely encompass the arms and serve not only to connect the loop 45 with the arms but also to maintain the arms in proper spaced relation and to brace and strengthen them. Moreover, the loop 45 extends out of way of the section 30 of the clamp for a purpose which will presently appear, The loop 46 includes extensions 50 disposed to lie against the inner faces or sides of the arms 33 and a of the section 30*. The extensions 50 are then bent up around the arm 34 and the terminals of these extensions 50 are engaged with the upper arms 33, as indicated at 5.1 in Figure 42. In this manner the extensions 50, serve both to, connect the loop &6 to thesection 30 of the clamps and alsov to, brace and strengthen thearms 30 and 3 L and hold these arms in proper spacedrelation.

In practice the clamps, 30 are arranged with their sections 30 and 30} embracing the spoke and. in clamping engagement. with the spoke under the, action o fthebolt. 37

and nut, Preferably the. head. oi the 9 3 S e Se t at th s head may coact with a screw driver or the like, the nut 28 being held from turning by engaging the arms 31 and 32. When the clamp has been properly positioned on the spoke, the hook 21 is engaged with the loop 4:6 ot the :clamp and the chain 16' is then extended around the tire and the snap hook 27 is brought into engagement with the loop 45. The manner in which the loop 45 is arranged with. respect to the clamp provides for the requisite clearance for accommodating the spring clip of the snap fastener. The shank 22. of the hook 21 is adjustable in its connection with the end link 17 thus the chain may be tightened or the length thereof may be varied to suit. the requirements of different makes, of tires.

I claim:

1. In. an anti-slipping device of. the character described, a chain, means fer securing the. chain to a spoke including a spoke connector comprising a pair ofclamping sections, each section being made up of a single piece of wire looped to, form upper and lower arms, the portions of said sections adjacent the bights of the loops being offset to provide seats and the terminals of the wire making up each loop being formed to provide apertured ears, a hinge pin, coacting with the apertured ears for pivotally connecting the sections together, a bolt. and nut coacting with the seats for moving the sectionsinto clamping engagment with the spoke, and a chain engaging loop. carried by each of said clamping sections,

2. An anti-slipping device for use on wheels comprising a. chain. adapted to be extended transversely around. the tire of the wheel. a snap. hook connected to one of the end linksv of the chain, the other end link having a pair of eyes, a hook having a shank provided with a series ofopenings adapted to vbe selectively alined with the eyes of the end link, a pivot pin cooperable withv the eyes and. the alined opening of the shank whereby the hook is adjustably connected to the chain, said hook also having an open bill and a spoke connector including sections, and means for clamping the sections. in. engagement with the spoke, said? sections carrying loopsv adapted to be engaged. with the snap hook and with the open bill.

3. In an anti-slipping device ofthe character, described, a chain, means for securingthe chain to a spoke including 2. spoke connector comprising a pair ofclamping sections, each section. being made up of 'ofifset to provide; seat srand the. termina s of the wire making up, each, loop. being formed;
